Contribution
It introduces the use of squeezed states formalism to analyze quantum fluctuations in Affleck-Dine baryogenesis, providing new evolution equations for particle modes.
Findings
Quantum fluctuations significantly affect baryon asymmetry.
Expansion and parametric amplification modify fluctuation evolution.
Squeezed states formalism offers a novel approach to early universe quantum dynamics.
Abstract
Quantum fluctuations in the post inflationary Affleck-Dine baryogenesis model are studied. The squeezed states formalism is used to give evolution equations for the particle and anti-particle modes in the early universe. The role of expansion and parametric amplification of the quantum fluctuations on the baryon asymmetry produced is investigated.
